Global steelmaking capacity is expanding despite a fragile demand outlook. The latest projections place excess capacity at 745 Mt by 2028, roughly 319 Mt more than OECD Member countries currently produce. This divergence echoes the peaks recorded during the last steel crisis and signals persistent pressure on prices, capital allocation, and credit conditions across the sector. The imbalance is not a one-year anomaly; it reflects a multi‑year cycle of capacity investments, policy interventions, and shifting trade patterns that together shape the risk profile of the global steel market.

The central question is not merely how much capacity exists, but how the structural imbalance rewrites the dynamics of supply and demand in steel and how policymakers should respond. The current trajectory hinges on a mix of subsidies, export strategies, and policy measures that distribute risk unevenly across regions and firms. In this context, the issue of global steel excess capacity transcends volumes to become a question of market structure, governance, and resilience within the international trading system.

The direction of travel matters because the bulk of new capacity has been added outside the OECD, frequently supported by government subsidies and other interventions. In 2024, Chinese steel firms received subsidies that, on median terms, were 15 times larger relative to asset size than those of peers elsewhere. When domestic markets cannot absorb output, producers pivot to export or to downstream products, depressing international prices and squeezing rivals who rely on export-oriented profitability. China, while not expanding capacity aggressively in recent years, has sustained a significant export push driven by weak domestic demand. Chinese mills shipped a record 131 Mt of steel to foreign markets in 2025, roughly 14% of crude steel production that year, marking a 153% increase from 2020. The country is now signaling an expansionary path again, with up to 38.6 Mt of new capacity planned through 2028, a figure larger than the current capacity of Italy, and among the largest nationwide expansion plans anywhere. Whether closures will offset these additions remains highly uncertain and depends on global demand shifts and policy responses elsewhere.

Analytics‑driven view of global steel excess capacity

The analytics frame highlights a capacity addition path that still looks very active through 2028. Planned additions of up to 138.8 Mt through 2028 represent a 5.7% increase from 2025 levels. This projection sits against a demand backdrop that remains sluggish, with global demand growth forecast at about 0.9% per year through 2030. In other words, the supply-side expansion is not matched by proportional demand growth, increasing the risk that utilization rates will stay subdued and fluctuate around the mid‑70s percentage points range for several years.

From a structural perspective, the global steel market is undergoing a reallocation of capacity that discriminates across regions. The OECD area experienced a marginal capacity contraction of 2.8 Mt (-0.4%) during 2021–2025, with pronounced declines in the United Kingdom (−39.7%) and Japan (−7.2%). These declines reflect both aging assets and policy pressures to tighten import surges; yet, the OECD is increasingly mobilizing policy tools to reverse this trend, signaling a future shift in the balance of supply discipline and protective measures. At the same time, non‑OECD regions drive most of the capacity growth, supported by subsidies and policy support that lower the hurdle for new plants and upgrades. The result is a bifurcated world: a mature, tighter OECD with more aggressive import controls, and a rapidly expanding non‑OECD landscape that adds capacity at a pace difficult to match with demand.

The demand side of the equation is subject to multiple headwinds. The Middle East conflict, higher energy prices, and persistent supply chain disruptions raise the cost of steel and tension downstream investment decisions. Against this backdrop, the global steel industry faces a delicate balancing act: how to absorb rising capacity without triggering a relentless price war or a credit crunch for producers with large debt stocks. The data imply that the industry will rely more on regional reallocations and foreign markets as a way to diffuse capacity into global trade channels, albeit with increased exposure to policy shifts and trade frictions.

Another layer of complexity comes from the fact that a large portion of capacity expansion has hinged on public support. In 2024, the median Chinese producer captured subsidies that dwarfed those of most peers external to China. Subsidies, subsidies-driven investment, and policy preferences create a cycle where expansion begets export push, which then pressures global price levels and invites retaliation through anti‑dumping and other trade measures. The consequence is a paradox: more capacity in a world of slowing demand raises the probability of price instability and capital misallocation, with the risk of prolonged underutilization across multiple plants.

From a market efficiency standpoint, the combination of subsidy-driven capacity, export intensity, and tariff‑ and non‑tariff‑based protection produces a situation in which marginal plants—especially those with higher operating costs or less efficient technology—face outsized competitive pressure. This dynamic suggests a need for structural adjustments that align capex decisions with credible, mid‑term demand trajectories, or risk a cycle of asset write-downs and financial distress across lenders and investors. The global steel market thus faces a critical window to re‑anchor capacity to durable demand signals and to calibrate policy tools to avoid a protracted misallocation of capital.

Within this context, the overall trajectory of the global steel excess capacity remains sensitive to policy‑driven actions, both in terms of how measures are designed to deter circumvention and in how they influence investment behavior. The empirical patterns show that even when import restrictions bite, traders seek workarounds, leveraging product variety and cross‑border flows to keep markets liquid. These dynamics matter because they shape the effectiveness of trade measures and the resilience of steel supply chains against shocks.

Contrasting perspectives on capacity expansion and demand

Regional dynamics vary sharply. China’s export push, supported by a broad product spectrum and aggressive pricing, contrasts with OECD members’ attempts to reconstitute more protective trade regimes and to monitor imports with greater precision. The divergence is not merely geographical; it reflects different policy ecosystems and industrial strategies. China’s approach has elements of both resilience against domestic demand weakness and strategic capture of global market share, while OECD countries pursue measures intended to stabilize domestic industries and terms of trade for their producers. In this global tug of war, the global steel excess capacity becomes a question of who shapes rules and who bears the cost of inefficiency.

The OECD landscape has shown some capacity contraction and structural re‑balancing, but this trend is fragile in the face of continued non‑OECD expansion. Between 2021 and 2025, OECD capacity slipped slightly, even as demand pressures outside the OECD intensified. India illustrates a different path: capacity expanded by 41.4 Mt in 2021–2025 and could add up to 31.8 Mt more by 2028, yet domestic demand remained robust enough to turn India into a modest net importer in the near term. Southeast Asia also demonstrates strong expansion, signaling a regional hub for capacity growth that will feed both local demand and export markets. The result is a multi‑tier geography of capacity and demand, complicating global optimization efforts for producers, lenders, and policymakers alike.

Trade policy responses have intensified in 2025, with antidumping (AD) and countervailing duty (CVD) actions remaining elevated and broader measures covering wide ranges of steel products gaining ground. Nearly 400 active AD/CVD measures were in place in 2025, with 75 new investigations that year alone. Yet, the analysis from OECD partners suggests that these measures are being sidestepped through product diversification, re‑engineering, and cross‑border supply chains. A striking pattern is that after OECD actions against Chinese steel in 2023–2024, imports from China declined in those markets, but in 88 cases Chinese exports to ASEAN countries rose, and in 51 cases ASEAN exports to OECD markets increased as well. A contemporaneous 300% surge in China’s semi‑finished steel exports to Southeast Asia underscores a channel through which raw materials are processed in third markets and re‑exported to evade targeted orders. The breadth of product categories—more than 3 500 grades—further complicates enforcement and incentivizes policymakers to move toward sweeping measures that are harder to circumvent.

Another layer of complexity comes from inputs, where trade restrictions on critical inputs such as chromium and nickel ores are becoming more common. Scrap, essential for electric arc furnace (EAF) steelmaking, is increasingly treated as a strategic commodity with 42 countries restricting its exports. As battery, energy transition, and defense demand grows, the competition for these inputs could intensify, creating new tensions between export controls and domestic industrial ambitions. This dynamic points to the vulnerability of production costs and the necessity for more integrated material security strategies within national steel policies.

The overarching implication is that the policy environment is shifting toward broader, more aggressive measures aimed at protecting domestic capacity and employment, while trade patterns exploit gaps and loopholes to bypass targeted restrictions. This tension underlines why the global steel excess capacity persists and why the policy playbook must evolve beyond ad hoc measures toward a coherent, enforceable framework.

Causal dynamics driving the imbalance

The causal chain begins with capacity investments that respond to long‑horizon expectations about demand, subsidies, and geopolitical risk. When governments subsidize new plants or expansions, they alter the expected return on capital, encouraging pace and scale in capacity growth that can outstrip credible demand forecasts. The immediate effect is to widen the production ceiling, lowering marginal costs for producers able to access subsidized finance and favorable regulatory environments. The weaker a country’s domestic demand, the more likely output shifts toward exports or downstream uses, which then interacts with global price formation and import protection policies.

Scrap and other inputs add another layer to the causality. Scrap remains a key input for EAF steelmaking, and restrictions on scrap exports influence raw material prices, plant utilization, and the geographic flow of production. In an environment of rising input controls, producers may seek to locate capacity where scrap and energy prices are most favorable, reinforcing regional shifts in the production map. The result is a self‑reinforcing cycle where capacity expansion in one region depresses prices there, prompting further capacity growth elsewhere in order to maintain share and profitability.

The structural driver at the core is governance misalignment. When policy incentives favor expansion without commensurate demand, the market experiences slower utilization and higher financial risk. The consequences cascade through debt covenants, capex planning, and lender appetite for steel projects, increasing the probability of asset impairment during downturns. In sum, the root cause is not simply an oversupply statistic but a mismatch between investment incentives and credible demand signals that persists across cycles.

Policy fractures also contribute to a fragile equilibrium. The Global Forum on Steel Excess Capacity (GFSEC) and the OECD Steel Committee are developing a framework for joint action to address root causes and negative effects, while strengthening import monitoring and detection of suspicious trade patterns. These efforts aim to align incentives, reduce circumvention, and foster a more stable investment climate. The challenge is to translate this framework into enforceable actions that withstand the political economy pressures that fuel capacity expansion.

Expert reconstruction: what needs to change to reverse the trend

Expert reconstruction starts with a commitment to policy coherence and credible enforcement. A durable turnaround will require stronger, more transparent monitoring of capacity additions, subsidization, and the true absorption capacity of national markets. The GFSEC framework should be complemented by practical tools to identify circumvention patterns in real time, reduce information asymmetries, and deter strategic exports that undermine protective measures.

• Policy coherence: align industrial policy with credible demand projections, ensuring subsidies and capacity expansions are conditional on absorption capacity and realistic utilization targets.
• Trade enforcement: enhance monitoring systems to detect and deter circumvention, including product diversification, serial modifications, and third‑country processing routes.
• Material security: coordinate policies on scrap, chromium, nickel, and other vital inputs to avoid artificial price spikes or supply bottlenecks that distort global competition.
• Industry consolidation: incentivize efficient capacity retirement and consolidation to reduce low‑productivity assets and improve average plant utilization.
• Investment signal alignment: ensure that long‑term capex plans are aligned with medium‑term demand trajectories and decarbonization objectives that influence steel mix and energy intensity.

Near‑term actions should emphasize monitoring and adjustment rather than blanket protection. An effective mix of targeted measures and market‑based reforms can improve utilization without triggering political backlash or policy lurches. The overarching aim is a more resilient steel ecosystem where capacity is matched to demand, enabling sustainable profitability for investors and stable prices for buyers.

Longer‑run reforms require a global governance approach that coordinates data sharing, capacity tracking, and enforcement across borders. The aim is not only to reduce excess capacity but to create a market environment in which investment decisions reflect real consumption patterns, technology improvements, and environmental constraints. In this sense, the path forward hinges on a combination of disciplined policy design, robust monitoring, and credible enforcement that can withstand cyclical shocks and strategic challenges from competing regions.

The global steel excess capacity problem is not something that can be solved by a single policy lever or a regional shield. It requires a coordinated, multi‑layer strategy that couples financial discipline with market‑oriented reforms, while preserving the flexibility needed to adapt to technology and demand shifts. If policymakers and industry players act with disciplined restraint and transparent governance, the next cycle can be steered toward a more stable equilibrium that preserves productive capacity while reducing the risk of disruptive cycles and price volatility.

In the end, aligning capacity with durable demand, closing loopholes in trade measures, and fostering coherent international cooperation will determine whether the global steel market can escape the current excess capacity trap and enter a more constructive phase for investment, employment, and growth.

Closing the gap with region-informed actions

Global capacity expansion continues against a sluggish absorption path. The most critical shortcoming is the absence of region-specific absorption targets and transparent milestones that tie subsidies and capacity expansions to actual demand. Without such targets, capital allocation remains exposed to policy cycles and mispricing risks. This section provides a compact, region-aware action framework with practical scenarios for policymakers and industry.

The most actionable improvement lies in pairing capacity plans with absorption checks, using regional demand signals and decarbonization trajectories to calibrate investment. This ensures that growth in steelmaking translates into real jobs and productive capacity rather than idle plants and stressed balance sheets.

Analytical note: this regional map shows how non-OECD growth concentrates capacity in markets with lower marginal costs but higher exposure to global policy swings, while OECD regions face aging assets and tighter import discipline.

Near‑term actions and metrics

• Condition subsidies on absorption benchmarks and credible utilization targets.
• Enhance monitoring to detect circumvention and cross-border processing routes.
• Coordinate material security for inputs like scrap and alloys to stabilize costs.
• Promote consolidation and retirement of low‑productivity plants to lift industry efficiency.

Analytical takeaway: this magnitude signals the need for a credible absorption framework and disciplined repair of investment incentives to prevent persistent misallocation and price instability.

Analytical note: the timeline emphasizes credible limits to expansion and a move toward market-oriented reforms with measurable outcomes.

The final tier of reform focuses on credible governance, comprehensive data sharing, and enforcement that can withstand regional political economy pressures while supporting a resilient, decarbonized steel sector.

What is the main gap in governing global steel capacity and how can it be closed?

The core gap is the absence of region-specific absorption targets and transparent milestones that tie subsidies and capacity expansions to actual demand. To close it, policymakers should implement region-aware metrics, require absorption-based subsidies, and align capacity plans with decarbonization trajectories and regional demand forecasts. This yields a clearer investment signal, reduces capital misallocation, and lowers price volatility over the cycle.

Analytical depth: a robust absorption framework improves capital allocation discipline and supports stable margins for lenders and producers alike, while enabling targeted reforms where absorption is strongest.

How should subsidies be conditioned to avoid misallocation?

Subsidies should be conditional on demonstrated absorption capacity, credible utilization targets, and documented demand signals at regional levels. They should sunset or step down as utilization improves, and be backed by independent monitoring to deter circumvention and the diversion of capacity into export channels that suppress domestic prices unjustifiably.

Analytical depth: conditional subsidies reduce risk by tying public support to measurable outcomes, encouraging retirement of underutilized assets and more efficient production.

What regional drivers most influence future capacity growth?

Non-OECD regions, especially India and Southeast Asia, drive the bulk of planned capacity through 2028, while OECD regions face aging assets and tighter import regimes. The implication is a more complex global map where absorption varies by region and policy alignment is essential for price stability and investment confidence.

Analytical depth: identifying regional absorption risks enables targeted policy to balance capacity with regional demand and decarbonization goals.

Which tools best balance capacity and demand in the near term?

The strongest tools combine transparent, demand-based subsidies; robust anti-circumvention monitoring; data-driven imports and anti-dumping enforcement; and secure input policies for scrap and critical materials. Coordinated international governance enhances credibility and reduces fragmentation, supporting steadier utilization and market stability.

Analytical depth: a credible policy bundle reduces volatility by aligning incentives with real absorption and decarbonization milestones.

How can demand absorption be improved to sustain long-term balance?

Absorption improves when policy signals match regional demand with modern steel use cases, financing for modernization, and incentives for high-value, energy-efficient products. Strengthening regional supply chains, scrap recycling, and circular economy practices reduces price swings and shifts investment toward productive capacity rather than speculative expansions.

Analytical depth: aligning demand with investment and decarbonization goals creates a more stable, resilient steel market over the cycle.
